APPARATUS 1F01?.` HANDLING ORE AND THE LIKE.

Applicationled April 27, 1921. SeriaI'No. 464,942.

This invention relates to improvements in apparatus for handling ore and the like and has for its principal object to provide a sim ple and durable conveying apparatus4 for 5 transporting loose material from one 'place to another as for instance in a mine.

In a prior application, Serial No. 382,696, tiled May 20, 1920, now-.Patent 1,462,688, July 24, 1923, I have disclosed an apparatus of the class above described comprising a scraper, and a movable frame adaptedto form a support about which Said scraper is guided. In the present application, I utilize the fsame general principles of construction and operation as therein described, but provide certain improvements in the construction of the scraper and draft ymeans used therewith, as will hereinafter more fully appear.4

` My invention may best be understood by reference to the accompanying drawings in which Figure 1 is a top plan View. Figure 2 is a. longitudinal crossesectionof `the scraper.'v Figure 3is a side view of the ap.- paratus shown in Figure 1 illustrating its use in a mine.

In the, embodiment of myinvention illustrated, the apparatus is adapted for use in mining operations in which loose material is to be transported from the working face, or place from which vthelmaterial is being mined, to a place where it may be loaded on mine cars. The loading apparatus commine bottom by means of suitable draft cables about a guiding frame 2 adapted to vbe fixed on the mine bottom in yposition to form a bearing for one side of the scraper as the latter is advanced into the loose material. In order to lillustrate the present' invention I have shown a. bearing frame similar to that shown and described in the prior applica# tion mentioned.` This frame is provided with a curved forward end 2a and a pair of slot 5 therebetween. rlhe forward end 2a is preferably provided with a -plurality of rollers 3, 3 and forms a guiding and bearing surface for the scraper 1.. The frame 2 is adapted to be held in place by means of a suitable guidingl device' such asa pair of jacks 6, 6a of the usualtype adapted to be inserted in the slot 5. The jacks 6, 6a are prises a scraper 1 adapted to be moved onvthe.,l

spaced apart so as lto restrain movement of `the frame in a lateral direction but allows movement thereof in a longitudinal direcf,

tion. Movement of the vframe is preferably accomplished by means of a draft device which may comprise a flexible cable 7 adapt- ,ed to be fixed at the forward end by some suitable anchor as for instance the jack GfVL and operated by means of a ratchet device comprising a', drum 8, and an operatinglever 8a. Itwill be understood, however, that any equivalent meansy may be provided ,for' moving theguiding frame forward with respect to theV fixed guiding jacks 6, and 6a as the loading operation proceeds. The scraper 1 is operated by means of suitable draft means, comprising a drag rope 9, and a tail rope 10, each connected with a suitable winding engine (not shown) located at a distance from the frame 2.l vrIhe scraper may be fof any suitable shape, but for the purpose of illustration I have Shown herewith a preferred form of scraper having a body portion 11 shaped in accordance with the scraper body shown and described in my co-pending application, Serial #1160,- 865, now Patent 1,464,522, Aug.- 14, 1923.

The present invention relates particularly to novel'means of attaching the head rope 9 to the scraper. Anarm 12 is attached to. a suitable transverse member 13 on the scraper 1. Said member is preferably attached to the scraper at or near the upper margin thereof so as not to interfere with the loading or unloading of the scraper. The arm 12 is-pivoted on a pin 16, to swing in a horizontal plane.

`An auxiliary provided if desired comprising a second cross member 14 mounted forward of cross member v13 and above; the arm 12, having a rearwardly projectingbrace 15 'attached to the pivot pin 16. The forward end 17 of the brace member may also be 'titl pivoted arm 12 is bent downward substan.- y

tially at iight angles asshown and is provided with a series of holes 18, 18, to anyone of which one end of dragline 9 may be suit- 1011 ably attached. By means of this 'arrangei and leap off t frame l' connected-with the winding engine, suitably located to move the scraper toward a load.-

ingjchute, `or the like.` Thescra'per'ispu'lled rearward bythe tail -rope about the guiding frame until the open end of the scraper' ll faces the pile of loose material, Inthis positio'n arm 12 will be swung laterally to one side 'and adjacent to the front face of the guiding frame as shown in Figure 1 thereof, leaving the front end of the scraper unob.-

structed for gathering the material. The scraper is loaded as it lmoves about the frame with one side thereof in lateral engagement with the frame. After the scraper leaves the frame Athe ivoted arm 12 assumesa longi Il tudinal posltion with. respect to the scraper sothat the latter is advanced forwardly to- 4ward the loading chute.q After the scraper Y is unloaded int is returned to its initial position by tail rope 10 and it is ready to collect another load. As the m terial within reach of the scraper is collected@ forwardby means `of the draftdevice 7 and the, ratchet 8 to advance the scraper into Athe fpile'. The head frame 2 mayybe moved into various positions as desired by placing the guiding jacks 6 and 6 as desired. The length of chain 19 which constitutes a portion of the head rope is provided because I- ind in practice that a liexible 'cablel of the :usual ty eis vliable to. whip1., about eliminated by jthefuseof the sh 'len' as shown.
